MR Neurology Perfusion Mismatch - Numaris X JobAid

MR Neurology Perfusion Mismatch The MR Neurology Workflow for Perfusion Mismatch is used to calculate the compara- tive values (mismatch) between the Diffusion ROI and the Perfusion ROI. The mis- match result may help to quantify the penumbra region. 1. From the Patient Worklist, load the appropriate data set into the MR Neurology Workflow a.

You can also load other im- age data in the left segments and create a mismatch evaluation of this data. (e.g., Dark Fluid TIRM and Diffusion data).
